Abstract: PURPOSE:To allow the user to use an inexpensive CATV tuner for a subscriber optical receiver by converting a frequency-modulated signal into an optical signal in response to a video signal subject to frequency multiplex processing so as to distribute the optical signal to plural subscribers. CONSTITUTION:Three kinds of video signals A, B, C are given to an optical transmitter 100, in which they are modulated into VSB-AM signals whose center frequencies are f4, f5, f6 respectively at AM modulators 101, 102, 103, they are synthesized by an adder 104 to be a frequency multiplex signal, which is fed to a VCO 105 whose center oscillating frequency is fh. After the signal is converted into an optical signal at a semiconductor laser 106, it is distributed to subscriber optical receivers 117, 118, 119 through an optical fiber transmission line 107 and an optical demultiplexer 110. The optical signal distributed to the subscriber optical receiver 117 is converted into an electric signal by a photoelectric converter, an FM detector 112 detects a frequency modulation signal to obtain a frequency multiplex signal.
